AUTOMATIC \VEATHER STRIP.

Application filed March 28, 1927. Serial No. 179,069.

This invention relates to an automatic weather strip.

Objects of this invention are to provide a novel form of weather stripfor windows, doors, and other similar members, which cooperates withthe'casing to which the windows are hinged and secures a weather-tightjoint therewith when such windows are closed.

Further objects of this invention are to provide a novel form of weatherstrip which is easily applied to windows with a minimum alterationthereof and which is equipped with a rocking sleeve carried by trunnionssecured to plates at opposite ends of the windows, one of the platescarrying a revolubly mounted rocking lever for operating the sleeve tothrow the weather strip into and out of contact with the casing.

An embodiment of the invention is shown in the accompanying drawings inwhich Figure 1 is a view from the inside of a window equipped withl, theautomatic weather strip with parts broken and in section to more clearlyshow the invention;

Figure 2 is a sectional view through a portion of the window and easingshowing the relative position of the operative parts.

Figure 3 is a detail, partly in section, of one end of the rockingsleeve;

Figure 4 is an inner face view of one of the end plates and theassociated mechanism, such view showing the rocking sleeve in section.

Throughout the description and appended claims, the term window isintended to cover a window, door, or similar member, and is used toavoid needless repetition.

Referring to the drawings, it will be seen that the window 1 is hingedlycarried by the casing 2 and is provided with a channeled lower portion,as indicated by the reference character A pair of end plates 4 and 5 areset into the edges of the window, as shown in Figure 1, and each platecarries an inwardly projecting trunnion which consists of a screw 6 anda revolubly mounted roller 7 carried thereby. Preferably, the screws areeach provided with spacers 8 upon which the rollers are carried, asshown in Figure 1. These rollers carry a rocking sleeve. 9 which isslidably and revolubly supported by one of the trunnions and is lockedto the other rollers by means of a screw 10. The last mentioned rolleris provided with an upwardly extending forked lever 11, as

shown most clearly in Figures 2'and 3. The sleeve 9 is provided with ametal weather strip 12 which is resilient and which is partially wrappedaround the sleeve and secured thereto at its end 13, as indicated inFigure l, so that there is ayield when the weatherstrip contacts withthe window casing, as shown in Figure 4.

The plate 5 carries a rocking lever-14 (see Figure 2) which is providedwith a rounded head 15 fitting within thesocketed lever 11, The otherend of the lever 14 is provided with a rounded face 16 adapted to engagea projecting stud 17 carried cured to the window casing, as shown inFigure 2. Preferably, the plate 5 is provided with notches 19 onopposite sides thereof into which the lug or projecting portion 17 mayfit. The plate is also provided with a pair of spaced stops 20 againstone of which the lever 14 rests, under normal conditions when the windowis open, and against the other of which one end of a U-shaped spring 21bears. This spring bears at its other end against the lever 14, as shownin Figure 2, and is preferably retained in place by means of the, screw22.

It will be seen that when the window is closed, the projection 17strikes the face 16 of the lever and rocks in a counter-clockwisedirection, as shown in Figure 2. This rocks the sleeve 9 and,consequently, rocks the weather strip 12 into contact with the windowcasing, as shown in Figure 4, such weather strip yielding sufficiently,and securing a weather-tightjoint with the casing.

It is desirable that these devices be reversible toaccommodate differentmountings of windows. Accordingly, the lever 14 is so made that it canbe reversed with respect to the plate 5 and the spring may sin'iilarlybe reversed. The sleeve 5) can also be reversed, if desired, and theparts will then be in position to accommodate a window swinging in theother direction.

It will be seen that a very simple type of automatic weather strip hasbeen provided by this invention which will readily accommodate itself todifferent types of window mountings.

Further, in view of the sliding connection between one of the rollers 7and the sleeve 9, the device will accommodate itself to windows ofdifferent widths.

Although the invention has been described in considerable detail, suchdescription is by a plate 18 seintended as illustrative rather thanlimiting as the invention may be variously embodied and as the scope ofsuch invention is tobe determined as claimed.

I claim:

1. In a device of the class described, the combination of a casing, amember hinged thereto, a lever pivoted intermediate its ends within saidmember, a rocking sleeve extending transversely along the underside ofsaid member and having an arm interfitting with the lower end of saidlever, .a spring urging said lever in one direction, means carried bysaid casing against which said lever strikes for rocking said lever inthe other direction to thereby rock. said sleeve, and a resilientweather strip carried by said sleeve and contacting with said casingwhen. said sleeve is rocked.

2. The combination of a casing, a. window hinged thereto, a plate set inthe side of said window and having a pair, of spaced stops, a leverpivoted intermediate its ends to said plate, a spring, one end of whichbears against one of saidstops and the other end of which bears againstsaid lever and forces said lever against the other of said stops, aprojection carried by said casing for engaging sai'd lever, and arocking weather strip carried by the ldwer portion of said window andactuated by said lever, said weather strip contacting with said casingwhen said window is closed, said lever, spring and weather strip beingreversible.

3. The combination of a casing, a window hinged thereto, and having achanneled lower end, a pair of plates set into opposite sides of saidwindow and having trunnions projecting towards each other and into thechannel in the window, a rocking sleeve revolubly mounted upon one ofsaid trunnions and'slidably and revolubly carried by the other of'saidtrunnions to accommodate variations in the width of thewindow, aresilient weather strip partially wrapped around said sleeve andsecured. thereto and adapted to rock into contact with the lowerportionof said casing, a leverpivotally car ried by one of said plates forrocking said sleeve, and a projecting member carried by said casing foractuating said lever when said window is closed.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of W'isconsin. V
